摘　　要：分析了双级压缩制冷系统的制冷系数及其影响因素以及低压级和高压级吸气过热度对系统的影响。对系统设计与调试过程提出了建议与要求。The refrigerating coefficient of performance （e） and its affecting factors of it in two - stage refrigeration systems is discussed . Then the influences of the superheat degree at the low / high side of the refrigeration system were theoretically analyzed and practically verified. Some requirements and regulations relating the system designing and debugging processes were presented at the end of the paper.
